COMBINED COVER AND STOPPER FOR METAL CANS.

SPECIFICATION forming part of Letters Patent No. 240,593, dated April 26, 1881. Application tiled January 11, 1881. (No model.)

To all whom @t may concern Beit known that I, FRANCIS W. HUNT, of Brooklyn, in the county of Kings and Stateof New York, have invented a new and Improved Combined Gov'er and Plug or Stopper for Metal Cans, of which the following specification is a description.

This invention is in the nature ot' an improvement in covers for metal cans, and is particularly adapted to milk-cans, the object being to produce a combined cover and stopper or plug for a can, constructed so that it can be easily inserted in the mouth of the can, and as easily removed, but serving, when in place, to tightly close the mouth of the can, preclude the churning ofthe contents, and prevent the cover falling oit or slipping out of place by the accidental upsetting of the can, or by unusual shocks or jars to which it may be subjected during transportation.

In the accompanying drawings, Figure l is a central vertical section of a can constructed according to my invention. Fig. 2 shows a modification of the construction ofthe neck or mouth of the can.

Similar letters of reference indicate correspondiu g parts in both figures.

A designates the body of the can, and A the breast, made in the usual way.

B designates the neck, and B the bowl o f the neck. The neck Bis sprung over the top of the breast, and soldered thereto on both sides, and the bowl Bfits into the neck and is soldered to the same.

C designates the cover of the can. It is stamped up in one piece, and is provided with a beaded rim, lc. A stopper, S, is soldered to the under side ofthe cover C.

The neck or lnouth B and the plug or stopper S are screw-threaded, instead of perfectly cylindrical, as heretofore. e

The neck B may be made of either corrugated sheet metal, as shown in Fig. l, with a band, b, of sheet metal outside of said threaded portion, or the entire neck may be made solid, as shown in Fig. 2, with the internal thread, e, formed by cutting, or in any suitable manner. This neck B is attached to the top of the can A, as stated, so as to occupy the position and perform the functions of the ordinary neck or mouth.

The plug `or stopper .SiA is made, preferably, of sheet metal, and instead of being smooth on its periphery, like the ordinary plug or stop-= per, it is externally screwthreaded, to vcorrespend with the internal thread of the neck B. A circumferential shoulder, m, is formed on the plug or stopper S, above the screw-threaded portion, ot' a width sufficient to overlap a shoulder, m', formed by the upper edge of the thread on the neck B, so as to entirely close the mouth of the can when the stopper S `is screwed down as far as it will go. The bottom or tip of the plug, in the example of my invention shown in the drawings, is entirely closed, so as to have the same effect as a perfectly solid stopper; but instead of this construction I may employ an independent stopper, to lit within the mouth of the plug or stopper S, or I may leave the mouth of the plug or stopper S entirely open. The beaded rim 7c of the cover Cfacilitates the turning ot' the plug or stopper, and the insertion of the same in, and withdrawal from, the mouth ofthe can.

By this invention I produce acombined cover and stopper for metal cans, by means of which the cover can be securely held in place on the can, when the same is being handled or transported from place to place, without necessitating the use of chains, locks, or other fastening devices. It also serves, by means of the shoulders m to tightly close the mouth of the can, so as to protect the contents against the action ofthe outer atmosphere, and when the mouth of the plug or stopper S is provided with a tip to close the same it will, when properly screwed downto its place, prevent any agitation of the contents of the can.

What I claim as my invention, and 'desire to secure by Letters Patent, is

l. The combination, an internally-threaded neck or mouth, B,hav ing the shoulder w', of the cover C, having the beaded rim k, and an externally-threaded plug or stopper, S, made of sheet metal, and provided with a shoulder, w, substantially as described, for the purposes specified.

2. The combination, with a can, A, having an internally-threaded neck or mouth, B, having the shoulder zo', of the cover C, having the beaded rim k, and an externally-threaded plug or stopper, S, made of sheet metal, and provided with a shoulder, a', and having its tip or lower end closed, substantially as set forth, for the purposes described.
